EVENT TEXT

PART 21 INVOLVING POSSIBLE ITT INDUSTRIES TRANSDUCER FAILURES

Since the date of discovery, design alternatives continue to be evaluated.

The methods under investigation for corrective action will be mechanical in nature. ITT Conoflow expects to conclude the analysis phase of their investigation by 12/15/00 and currently estimate that replacement units would be available by 2/15/01.

Advice to Customers

Each site location should analyze their system and corresponding potential for failure with regard to this notification. In the absence of a seismic event resulting in radiation and/or a steam line break, they do not believe this unit will cause an operational problem.

Please note that the product qualification was simulated for a ten, (10) year design life. Those units with a service life of ten, (10) years or more should not be considered qualified.

Individual customers will be advised by letter when replacement IEEE I/P transducers are available.

Nature of the Deviation

The nature of the deviation is to the test and performance requirements associated with IEEE 323 and IEEE 344. An inappropriate bonding process was utilized in the manufacture of the IEEE I/P Transducer. This process change began in 1986 and could, during a seismic event involving high radiation and/or high temperature steam, result in the potential failure of the transducer to perform its intended safety function.
